Parameters Determining the Properties of Polyhedral Alumina Hollow Sphere

With the continuous improvement of people's water treatment standards, especially in some northern cities, it is widely used in water treatment. Multi-faceted hollow ball packing is a kind of water treatment material with good performance. Filter material manufacturers are also constantly improving the multi-faceted hollow ball. performance parameters, so which parameters determine the performance of the multi-faceted hollow sphere? Alumina hollow sphere manufacturer Xiaobian will talk about it.

There are generally three parameters that determine the performance of multi-faceted hollow spheres, namely geometric shape, specific surface area, and oil absorption value.

1. The geometric shape of the multi-faceted hollow ball filler is one of the important factors for its performance. Because the multi-faced hollow ball receives various external forces during the production and transportation process, its shape is not a regular circle, and some are squeezed by external forces. If it is pressed into an ellipse or even flattened, the performance of these multi-faceted hollow spherical packings will be greatly reduced or even damaged. Therefore, the original geometric shape of the multi-faceted hollow spherical packings must be maintained during production and transportation.

 2. The second parameter that determines the performance of the polyhedral alumina hollow sphere packing is the specific surface area, which refers to the surface area of ​​the polyhedral hollow sphere packing per unit mass. In fact, multi-faceted hollow ball fillers rarely have smooth surfaces, and some are even riddled with holes and unevenness, making it difficult to find out the rules. The size of the specific surface area is directly related to the affinity between the polyhedral hollow sphere filler and the matrix resin, and the activation treatment of the surface.

 3. The oil absorption value is the third parameter that determines the performance of the multi-faceted hollow ball filler. When the multi-faceted hollow ball filler and the plasticizer are used together, if the plasticizer is absorbed by the multi-faceted hollow ball filler, it will greatly reduce the effect on the resin. plastic effect.
